Tie-line and level-law calculations show that low-carbon ferrite nucleates and grows, leaving the remaining austenite richer in carbon.

由截线及杠杆定律分析可知，低碳铁素体成核并长大，剩下含碳量高的奥氏体。

To achieve this aim, one has to studying the growth mechanisms of CNTs, finding out how CNT nucleates, why growth teminates, how to control the diameter and chirality etc. Thus the goal of this study is to clarify the growth mechanisms and achieve controlled synthesis of CNTs.

而要实现这一目标，就必须研究清楚碳纳米管的生长机理，弄清楚碳纳米管是如何成核，为什么生长自动终止，如何控制管径，如何控制螺旋度等问题。

During solidification,α-Al phase nucleates first in the interstices between the short fibers and grows gradually toward the surface of Al2O3 short fibers. The content of Cu and La element around the surface of Al2O3 short fibers increases, both of them enrich almost in the same region, but the content of Cu element in the interstices of short fiber decreases gradually.

结果表明：Al2O3纤维与基体间润湿良好，生成了致密的界面层；在凝固过程中，α-Al相在短纤维间隙中形核并向纤维表面生长，纤维表面Cu和La元素的浓度增大，纤维间隙中的Cu元素的浓度减小。

It is found that substructures of stress-induced εM are γlamellas and stacking faults. A new growing mechanism of stress-induced εM were raised, that is ε phase nucleates at many sites on parallel γlamellas and stacking faults,εM unit-layers join each other in length and combine in width.

并据此就ε马氏体的形成长大机制提出新的观点：εM相形成时先在层错和γ夹层处多位置形核，然后以εM单元层长度方向彼此相接、宽度方向相互合并的方式长大。

Theoretical study on the change of HOMOs and LUMOs gaps illustrates that cubic-like structures are more favorable than others growth modes, namely the cubic zirconia nucleates favorable, this fact accords well with previous experimental results.

对各种生长模式的最高占据轨道能和最低空轨道的能量的差值与团簇的尺寸变化可以发现，氧化锆团簇最容易以类立方结构的生长模式生长，即立方相氧化锆团簇结构容易形核生长，这是符合先前的实验结果的。
